UNIT 4 LESSON 3 MOUNTAIN BUILDING NOTES
1. Tectonic plate –
2. Deformation –
3. Stress -
A. Give two reasons why rock would break rather than bend when under stress.
1.
2.
b. Give a reason why a rock would bend rather than break under stress.
4. When a rock breaks a ______________________- forms.
5. When a rock bends a _______________________ forms.
6. Folding -
7. Fold -
8. Anticlines (define and draw a picture) -
9. Synclines (define and draw a picture) –
10. Fault –
11. Fault blocks –
12. Fault plane –
13. Hanging wall (define and draw) –
14. Foot wall (define and draw) –
15. Strike-slip fault – (define and draw) –
16. Shear stress (define and draw) –
17. Strike-slip faults are common at ____________________________- boundaries. The __________ ______________
fault system in CA is an example.
18. Normal fault (define and draw) –
19. Tension stress (define and draw)
20. Normal faults are common along ______________________________ boundaries. The _________________ and
____________________________ area of the southwestern US is an example.
21. Reverse fault (define and draw) –
22. Compression stress (define and draw) –
23. Reverse faults are common along ______________________________ boundaries. The __________
_________________________ Mountains in the US are caused by reverse faults.
24. Mountains can form through _________________________________-, _________________________________,
and ________________________________________.
25. Uplift –
26. Folded mountains form when rock layers are ________________________________ together and pushed _______.
27. Folded mountains usually form at _____________________________ boundaries.
28 The __________________________________- ____________________________ were formed this way. They
formed from folding and faulting when the North American plate collided with the Eurasian and African plates millions
of yrs. ago.
29. Volcanic mountains form when ____________________ _________________ erupts onto Earth’s surface. Many
major volcanic mountains are located at ________________________________ boundaries. They can form on
______________________________ or on the ___________________________floor.
30. Volcanic mountains that form on the ocean form can get so big they become volcanic _____________________
31. Most of Earth’s active volcanoes are concentrated around the edge of the Pacific Ocean. This area is called the
_______________________________ __________- _______________________________.
32. The ____________________________ mountain range in the Northwest US. were formed this way. One of the
more famous US volcanoes is in this range, ________ _______________________ __________________ . (Not in the
book.)
33. Fault-Block Mountains form when ______________________ makes the lithosphere break into many
____________________________ faults. Along the fault pieces of lithosphere _________________ _____________
compared with the other pieces. The pieces left _____________________________ form fault-block mountains.
34. The _____________________________- _________________________ and the _____________________
___________________________ are fault-block mountains.
